A previously unreported Lebanese Hezbollah flag is shown in this photo
on a blog [source].
According to the blogger, it is the flag of the Lebanese Islamic Resistance, which is apparently the armed wing
of Hezbollah (a fact which came as something of a suprise to me, as I'd always been
under the impression that Hezbollah was the armed wing of Hezbollah.)

A better image of the logo is shown here.
Oddly enough, while the "civil" Hezbollah flag contains a Kalashnikov, its military wing limits itself to an old-fashioned fountain pen.

On a yellow field, a circular logo comprising the outline of a dome (of a mosque?) or the upper part of a globe
sheltering a word in large, heavily-stylized red Arabic lettering, the text transforming into a red arm and fist
gripping the shaft of a white downward-pointed fountain pen, which is seemingly writing another line of black text.
